FIELD: mechanical engineering; welding. ^ SUBSTANCE: invention can be used in welding of metal structures in different spatial positions. Welding bath is formed at flat volt-ampere curve of supply source and rising volt-ampere curve of arc. Crystallization of metal in bath is carried out at drooping volt-ampere curve of supply source and flat volt-ampere curve of arc. ^ EFFECT: provision of synchronization of welding wire feeding with change of external volt-ampere characteristics of supply source. ^ 1 dwg |
